Similarity.Rubinoboletus rubinus is similar and might be confused with Chalciporus amarellus.Rubinoboletus rubinus however has different cap colour, spores of different size and shape, and grows under broadleaf trees.

Note. There are some taxonomical and nomenclatural problems with the name of this species. Klofac (2006) considers that the name Chalciporus amarellus is misapplied, while other obstacles prevent the use of other possible names. According to Klofac Chalciporus pierrhuguesii is not described in its “most typical appearence”, Chalciporus pseudorubinus is invalid and the delimitation of Chalciporus xanthocystis is based on inconsistent characters. Here, I prefer to keep the name C. amarellus until solution of this problem is achieved.
